Embodiment
In the cable duct sealing device of improvement structure as shown in the figure, two ends are respectively upper flange 1 and lower flange 2, and is the elastic sealed body 3 of annulus column between two flanges, also have several clamping screws 5; Clamping screw is for applying coupling mechanism force to two flanges, thereby utilize two flanges that elastic sealed body is fixed as one and (in one of them flange, is embedded with the nut 4 matching with clamping screw folder, clamping screw inserts from another flange, fixes after passing through elastic sealed body with nut screwing clamping).
Above structure and existing cable pipeline sealing device are roughly the same.
Improvement of the present invention is: on described seal, be manufactured with several and passed through the through hole 3-1 that runs through two end faces after whole seal, these through holes pass through (axis of through hole is parallel to the bus of elastic sealed body) for clamping screw, can to seal, realize reliably again fixing simultaneously, it is unlikely toward internal diameter direction or the undue slippage of external diameter direction, to guarantee the firm of structure.On described elastic sealed body, be also manufactured with after at least one the seam 3-2(annular wall portion that cuts open disconnection that its annular wall portion is disconnected the deployable one-tenth flat shape of elastic sealed body); It is to make the two ends overlap joint of cutting position open of elastic sealed body have slippage to a certain degree to regulate leeway afterwards that this object of cutting seam open is set, thereby makes elastic sealed body radially carrying out a certain amount of variation, thereby has adjusting leeway to a certain degree.
General, for meeting seal request, the seam of cutting open showing at elastic sealed body circumferential surface (is on Fig. 5, Fig. 7, to show it is to form the straight line of certain angle with radius for being parallel to busbar arrangement, on the periphery of elastic sealed body, be also the straight line that is parallel to bus), or helix shape (although be to show it is straight line on Fig. 5, Fig. 7, being the curve of helix shape on the periphery of elastic sealed body).Specifically by user, selected to determine.
